y `sTIcKINe Pins IN PAPER.

To all whom t may concern Be it known that I, CHAnLEs ATwooD, of the city, county, and State of New York, have invented a new and original Automatic Machine for Sticking Pins into Paper for Packing, of which the following description, illustrated by the accompanying drawings, is sufficiently clear and comprehensive to enable persons of competent skill to make and usemy invention.

`Figures l and 2 are end and side `elevations, and Fig. 3 is a top view.

The nature of my invention consists in `a new, original and automatic machine for sticking pins into papera single pin at a time, but using the old and well known device l called an inclined straight conductor or feeding channel for feeding thepins in a vertical or nearly vertical position down to what I denominate a double inclined plane separator which is attached to a viand point while the pin is in thenippen,

the driver or pusher having a lip which passes over the top of the pin sufficiently far to prevent its rising. By the continued action of the machine the nipper `retires for another pin and the driver immediately delivers the former one by pushing it laterally into a guiding groove ready to be inserted into the paper. The paper is crimped by the old and well known device of crimping bars without transversenotches,

the crimping bars standing vertical or upright with the side or edge of the paper projecting over the end of thebars a proper distance for each pin to be stuck, the pins beinginserted across the ends of the crimping bars, the latter assisting to preventthe pins in some cases from falling. The paper is coiled up upon a spindle and is stationed at considerable distance from the machine l upon a truck `or standard. It then passes through the intermittent rollers rising and falling and then passes from the rollers through the crimping bars to another spool parts of the machinery.

Motion is communicated to the several devices to perform the various movements necessary to effect the object proposed by means of a series of eccentric wheels or cams upon theshaft C. The eccentric D moves the rocking shaft E, which gives the circular and reciprocating motion to the pin nippers F by means of the slide bar G.

A reverse motion to this rocking shaft is kept up by the helical spring at e. The l lever H upon the fulcrum I, receives its lateral motion from the eccentric J :and operates the driveror pusher K; which slides in dovetail slot and is forked and pointed in such a manner as to receive the pin from the pin nippers F. l

M and N are another eccentric and lever for giving motion to the catch pin c of the pin nippers. This catch pin is made something after the form of a common crank with the hub sliding upon the rocking shaft E and the crank pin V passing through an arm of the pin holder F operates with the other arm to form the pin nippers. This part of the pin nippers V has a lip upon the end constructed with a double inclined point v1 for the purpose of separating the first pin in the conducting channel from the remaining ones, the point or corner of the lip entering within the free space near the head of the pin. The pin is thus clasped about midway of the body bythe nippers, which are kept closed the requisite time by the helical spring a upon the rock shaft O is another eccentric which carries the driver P through the guiding groove to stick the pin it has received from the lateral pusher K into the paper. The side ecentric wheel Q, operates the dog R, and ratchet wheel S upon the shaft T. The small i y such lever as vation by the rackY pinion and ratchet wheel spaces the distance betwen the separate pins.

A areV the crimping bars over which the paper passes. B is stationary and C is movable by the lever D operated by the eccentric wheel E and spring F.

G is a movable inclined plane resting upon and made fast to the bed piece A, by a foot and extending upward at a slight vertical inclination by the side of the roller X, and b y the fall of the roller the pins X. &c., successively each fall upon the incline and move the roller in advance to space the rows of pins.

H is a t-rip attached to the vertical side piece of the frame V, and serves to release the dog or dogs R, from the ratchet wheel S and at the same time to block or brace the lever D by means of the brace I.

J is an arm for releasing t-he brace on the falling of the rollers and roller frame.

The conducting channel K receives the pins from the hopper and guides them to the pin nippers already described. It has three springs 0 0 0 upon its side, two of which are self acting and retard the pins luntil taken by the nippers and' prevent their being so taken when the third spring is pressed by the stay lever L, operated by the upward motion of the frame V. The hook l releases the spring pressed by hereinafter stated. This spring 0 is not self acting upon the pins but in order to retard them requires a pressurefrom the wire finger N, erected upon the end of the lever N.

The operation of theu machine is substantially as follows: The pins are first received into the upper part of the straight conducting channel and by it conveyed downward till stopped by the check springs 0 0. As the nippers approach to'take the pin the pressure finger N advances by the action of the lever N, and presses upon the spring 0, which prevents all the pins but one from passing. The double inclined plane or dividing lip upon the nipper separates the pin thus presented from the next above it and by the action of the rocking shaft the nippers take it from beneath the springs o, 0, and convey it to the horizontal bed piece or railway, at which place it is in a horizontal position, being turned partly, upon the point as a center, by the nippers. I-Iere the driver or pusher K takes the pin and moves it horizontally to the guiding groove and deposits it beneath the pressure of the small spring holder y. The driver P here takes it and at the same time liberates the holder y and sticks the pins through the paper crimped by the crimping bars in the ordinary manner. 'It will be observed that the levers for performing the several operations necessary to set the pin in the paper and all these several operations for conducting the pin to its place of destination are performed by means of cams or leccentrics and by means of levers all operated and complete at one revolution of the driving shaft. Several pins are therefore being carried to the paper at the same time. The paper being also moved by the operation of the same shaft, its motion must correspond to it. The side eccentric wheel Q moves the dogs and by them the ratchets and racks already described so as to conduct the paper first around the roller X and then around X; from thence through the crimping bars, when the pins are stuck. As each pin is inserted the paper is elevated by the apparatus already specified sufliciently for the next succeeding one and when the row is completed vthe frame V elevates the stay lever L, causing the vertical arm of the same to press the spring 0 and prevent the pins from coming within reach of the pin nippers until the frame V falls by a release of the dogs from the ratchets by the trips above described. As the frame falls the hook M again releases the pressure friction lever L and thus again permits the flow of pins as before stated. After the paper has received the row the rollers and paper simultaneously fall and the vertically inclined lever or plane G carries the roller X and with it the paper and other rollers X X sufficiently far for another row by means of the pins X as already specified.

The vertical spool or roller y may be located at a convenient distance from the machine, placed upon a pedestal which may be detached from the main machine already described. The paper is first wound upon this roller in considerable quantities and then carried as represented around the roller X, then around the roller X and then through the crimping bars, at which place the pins are inserted,v and from thence the paper with the pins attached in the usual manner passes over the roller X and is carried to the spool Z dletached in like manner from the main machine and located upon a pedestal at such distance from the machine that the rise and fall of the rollers X, X, X and the frame in which they are hung will not interfere with the rolling or unrolling of the paper. It will be observed that the crimping bars are located below the groove near the paper, so that the pins may be stuck immediately over their ends, while they hold the paper fast.

What I claim as my invention isl. The vibrating nipper V armed with a knife or double inclined plane for separating the pins turning them from a vertical to a horizontal position as specied.

2. I claim the straight inclined conductorK when combined with the nippers V with their separating points, as carrier, as

` described.

3. I claim the lipped driver K for driv` ing the pin along a railway or bed laterally into the groove to be stuck into the paper, `when it acts upon the pin before the vibrating nipper lets go its hold.

4. I claim the lateral driver or its equivalent for the purpose of delivering the pin under the spring holder y, as a. means of controlling the pin until it is inserted into the paper.

5. I claim the combination of the stick! ing driver P audits guiding groove with `the vertical crimping bars when the bars permit the paper to pass over their ends vertically in the process of sticking pins.

6. I claim the feeding rollers Y, Z,or

their equivalents for the purpose of holding the paper and controlling it at such a distance from the guiding rollers X X X as will allow thepaper to pass up and down withoutmoving the spools while the rollers are in motion.

7. I claim the rollers and carriages which control pins and the paper for the purpose of moving the paper forward intermittently up and down intermittently to space off the rows of pins and to space the dis tance between each succeeding pin in the same row, the ends of the paper resting on spools Y Z dissected from the machine.
